Kadangi tokios vietos yra gerai apsaugotos nuo lietaus ir sniego ar kit\u0173 stichij\u0173, barzdot\u0173j\u0173 grif\u0173 statiniai ir juose susikaup\u0119 maisto liku\u010diai ilg\u0105 laik\u0105 gerai i\u0161silaiko. <\/p>\n

Nuo 2008 iki 2014 met\u0173 Margalida ir jo bendraautoriai analizavo 12 labai sen\u0173 barzdot\u0173j\u0173 grif\u0173 lizd\u0173 turin\u012f ir juose rado tikr\u0105 lobyn\u0105.

Daugiausia tai buvo maisto liku\u010diai, kuriuos barzdotieji atne\u0161davo savo palikuonims.<\/p>\n

Juose buvo 86 gyv\u016bn\u0173 kanopos ir daugiau nei 2100 kaul\u0173. Taip pat aptikta kelios de\u0161imtys kiau\u0161ini\u0173 luk\u0161t\u0173 fragment\u0173.<\/p>\n

Tyr\u0117jai lizduose rado ir \u017emoni\u0173 pagamint\u0173 daikt\u0173 \u2013 audini\u0173 bei \u012franki\u0173. Pavyzd\u017eiui, tarp j\u0173 buvo laidyn\u0117 (akmens svaidykl\u0117), pagaminta i\u0161 pintos \u017eol\u0117s.

Remiantis \u0161iais duomenimis galima atkurti, kuo \u0161ie pauk\u0161\u010diai maitinosi \u012fvairiais laikotarpiais ir kokiomis ekologin\u0117mis s\u0105lygomis gyveno. <\/p>\n

\u0160ie duomenys bus naudingi siekiant i\u0161saugoti barzdotuosius grifus, kurie nyksta. Barzdotieji grifai yra viena labiausiai nykstanti grif\u0173 r\u016b\u0161is Europoje. Teigiama, kad \u0161iuo metu \u017eemyne liko vos 309 perin\u010dios poros. <\/p>\n
